Did that consent banner actually stop the tracking requests, or just hide
the banner? Export two HAR network captures from your browser — one
before a consent choice, one after — and this diffs every request and
cookie that appeared or disappeared. Nothing is uploaded.
How to get a HAR file
Open your browser's DevTools → Network tab → reload the
page → make your consent choice (or don't) → right-click any request →
"Save all as HAR". Do this twice on the same site: once
before the consent action, once after, then drop both files below. Only
test sites you own or are authorized to test.

Third-party requests present in both captures
These carried on across the consent choice — the same endpoint was
requested before and after. This is usually the part of the report worth
reading first: a request that disappears is easy to spot, but one that
never stopped is what a consent check is looking for. Repeats of the same
endpoint are collapsed into one row. Requests to the page's own host are
counted below rather than listed, because a site's own assets are
expected to persist.

The export is a dated JSON file with this exact diff, the two source
filenames, and this disclaimer — a record for you to review, not a
compliance determination.
